Battery swapping is also not very accessible, not evening can lift 50+ pounds
Nio Inc. has videos of the process, and that's what you'd expect (and I assume what tesla tried at one time), you drive to a booth, the car gets locked in and the battery is replaced automatically, then you drive out.
This map has real time stats on battery swap. Unfortunately it's only available in Chinese. NIO has done 35 million battery swap to date and you can see where the swap stations are located. Not quite as accessible as your gas stations but not far off especially in the large cities.
